The idea, if implemented well, is amazing. Most helpful for typing in native languages, other than english. The software on the desktop can update / modify keys based on user interactions and options. Can anyone tell me of any vendors for those tiny e-ink screens? I have been looking forever for screens that can fit into a keycaps. edit: Even non e-ink screens are ok. edit: Upon closer inspection of the images, and more importantly, their library page, it looks like they have a giant e-ink screen and transparent keys. This is a clever design and I would consider it a win if the mechanical performance of the keys is on par with regular keyboards.
